eclaims. (Cl. 114-79) This invention relates to new and useful improvements in welded ships, and has more particular reference to an improved reinforcement for the plate thereof.

More specifically, the invention proposes the use of a plurality of substantially horizontal metallic strips vertically spaced from each other and welded upon the ship's hull for strengthening same longitudinally and for acting as a stabilizer. The strips engage the water and materially reduce rolling of the ship.

The invention proposes to extend the reinforcing strips from stem to bow of the ship, or a lesser distance if desired.

It is pointed out that the more strips used, the better the reinforcement and the stabilizing action. However, it is suggested that there be one strip for approximately each two feet of height of the hull, or one strip may be used for each horizontal seam of the plates forming the hull, or the strips may be used in between the seams.

The invention further contemplates several modified forms. a

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 6 is a fragmentary sectional view similar to Fig. 1 but illustrating a modified form of the invention.

Fig. 7 is another fragmentary sectional view similar to Fig. 3 but illustrating still another modified form of the invention.

Fig. 8 is a fragmentary perspective view of the parts shown in Fig. 7, certain of the parts being separated for illustrative purposes.

The reinforcement for welded ships, in accordance with this invention, is intended for seams of adjacent hull plates.

welded ships having an interior frame Ill and hull plates II welded to each other and mounted on the frame III. A plurality 01' substantially horizontal metallic strips I2 are vertically spaced from each other and are mounted on the hull plates II and preferably extend from the bow to the stern of the ship, and preferably all the way down to they keel. In Figs. 1 and 2, a ship I4 of any design and construction is shown provided with the reinforcement strips I2.

Each of the strips I2 is secured to the hull plates II by welding material I5 along the top and bottom edges. Each of the strips I2 is furthermore securedv to the ship at horizontally spaced points by rivets I6. These rivets are passes through the strips l2 through the plates II, and also through the frame I0.

Several modified forms of the invention are proposed. In the form disclosed particularly in Figs. 3-5, the strips I2 are set over the horizontal For example, the hull plates II and II are provided with a horizontal welded seam IT. The strip I2 is formed with a. horizontal recess I8 for engaging the seam II. In this way, the strips I2 reinforce the horizontal seams of the hull.

It is proposed that the strips I 2 be horizontally spaced from each other, preferably two feet apart, though this distance may be varied in accordance with design. It is further proposed that each strip I2 be approximately one inch thick and three inches high, though here again these dimensions may be varied. With the particular design proposed it will be found that the reinforcement strips I2 not only structurally reinforce the hull of the ship but also act as stabilizers to prevent or reduce rolling of the hull.

In Fig. 6 a modified form of the invention has been disclosed which is very similar to the prior form, distinguishing merely in the fact that reinforcement strips I2 are mounted upon the hull plates II at points in between the horizontal weld I! of the hull plates. The strips I2 are mounted in position by welded material I5 along the top and bottom edges. At spaced horizontal points, the strips I2 are also securely held by rivets I6 which are passed through the hull plates II and through the frame I0. Because the reinforcement strips I2 are not mounted over the seams of the hull plates, they do not need recesses at the back for accommodating the welded seams.

In Figs. 7 and 8 another modified form of the invention is shown which is very similar to the first form of the invention, distinguishing merely in the construction of the reinforcement strips I 2". In this form of the invention each reinforcement strip I2" is formed from two separate strip sections. There is a narrow bottom strip section I! and a muchwlder top strip section l2. The bottom strip section I! is formed with an outer top beveled face 20 and an inner groove 2|. This bottom strip section l2 is secured upon the hull of the ship with welding material 15' disposed within the groove 2|. Thetop wide strip section ll has a beveled bottom edge complementary to and engaging the beveled outer edge portion 20' of the bottom strip section 12 for locking the top and bottom strip sections together. The top strip section I2 is permanently secured to the hull by top welding material l5 along the top edge thereof.

In other respects this form of the invention is similar to that previously shown and like reference numerals identify like part in each of the several views.

An improved method is also proposed for attaching the reinforcement strips l2" in position. It is proposed to provide a protecting cover strip 24 removably mounted upon the top of the beveled edge 20 and the bottom strip section I2 It is proposed to weld the strip section I2 in position on the hull with the welding material IS. The purpose of the removable strip 24 is to protect the bevel 20 from accidental deposits of welding material. After the strip section l 2"- is welded in position it is proposed that the removable strip 24 be removed. This removable strip may be removably held by soft solder at spaced points or by tacky material, or other adhesive material which may be easily opened. When the strip 24 is removed the edge 20 will be clean and will be ready to receive the top strip section l2 which is then engaged in position. The top strip section i2 is then securely fastened by the welding material and the rivet Hi.

In other respects thi form of the invention is similar to that previously shown and like reference numerals identify like parts in each of the several views.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:

1. In a welded ship having an interior frame into which the seams of the hull plates may ensage. and rivets securing said horizontal strips to said hull substantially along their center lines preventing outward bulging of said strips between the secured edges.

2. In a welded ship having an interior frame and hull plateswelded to each other and mounted on said frame, a plurality of substantially horizontal metallic strips vertically spaced from each other and mounted upon said hull plates, at positions over the horizontal seams of said hull plates secured at their edges to said hull plates, said strips having recesses on their back faces into which the seams of the hull plates may engage, and rivets securing said horizontal strips to said hull substantially along their center lines preventing outward bulging of said strips between the secured edges and which engage through the strips and the hull plates and said interior frame.

3. In a welded ship having an interior frame and hull plates welded to each other and mounted on said frame, a plurality of substantially horizontal metallic strips vertically spaced from each other and mounted upon said hull plates, each of said horizontal strips comprising a narrow bottom strip having an outer inwardly inclined beveled face and an inner groove, said bottom strip being welded by welded material within said groove, and a wide top strip having a bevel complementary to and looking into said bevel, and said wide top strip being welded and riveted upon said hull plates.

4. A method for reinforcing a welded ship consistin in welding a plurality .of substantially horizontal narrow metallic bottom strips having an outer inwardly inclined beveled surface, said bottom strips being at vertically spaced positions from each other upon the hull plates of the ship by welding material placed within a top groove thereof and protected from engaging upon said outer top beveled surface by removable strips, removing said removable strips after said narrow bottom strips are welded in position, and engaging wide top strips upon said bottom strips, said top strips having interlocking faces with the bevel of said bottom strips, and welding said top strips in position.
